摘要：

We present an identity-based on-line/off-line singcryption scheme, where most of computations are carried out when the message is most available(i.e., offline stage) and the on-line part of our scheme does not require any exponent computations and therefore is very efficient. It combines the functionalities: of signature and encryption and is provably secure in the random oracle model. We also show that our scheme is indistinguishable against adaptive chosen-ciphertext attacks (IND-IDSC-CCA2) and is existentially unforgeable against adaptive chosen-message attacks (EF-IDSC-ACMA).
